SLS AMG Black Series to come in coupe and roadster forms with 650 horsepower, price around $300,000-$350,000

Autobild reports that the Mercedes SLS AMG will be getting a horsepower bump using the M159 (M156 variant) pushing 650 horsepower. For those counting, that will be an increase of approximately 87 horsepower over the standard SLS. That would also be 104 horsepower per liter which is a very impressive specific output for a V8 of that size. The other interesting bit of news is that it will not be limited to just coupes but supposedly will be available as a top down roadster. We'll see if AutoBild got this right soon enough, expect official details on the 2013 model year to come out in the next few months.

The specific output numbers are within reason. We will see, there have been some M157 rumors as well.

Only time will tell. There maybe changes to the internals to the M159. 87hp gain on the current M159 would require LT Headers, catless system and a good tune, which I'm sure they would not acquire this type of system for production.

What are you basing any of this on ?? Do you have any clue what you're talking about ? The internals on the M159 have already been upgraded from the standard M156, as well as the heads, numerous other things and dry sump lubrication. And it's no secret that this motor is very detuned from the factory - just like the M156 was. And the M156 with "long tubes, catless exhaust and a good tune" makes ~100 whp over stock. So it's not at all far fetched for the M159 to have an additional 87hp with some minor tweaks and more aggressive tuning from the factory...just like all Black Series variants

The factory could easily find gains in areas tuners would have more trouble with like the compression ratio, redline, valvetrain, cams, heads, etc.

Are you guys sure it's going to be M159. I have a feeling they will use a modified M157 TT engine on it. I don't know how they will get 87hp on a NA engine

Although I love the M156 and M159 engines, I'm really hoping that they will indeed use the M157 because then the tuning potential will be huge..... I wonder if this car will be on-par with the Ferrari 458 Scuderia

I think so too.... but the regular SLS didn't stack up too good at Famoso last year vs the Italia.... the SLS ran a best of 11.8 @ 123 mph while the 458 Italia ran 11.0 @ 129 mph (same day same track). I don't know exactly what was contributing to such a big gap in time between them (0.8 seconds) aside from weight as they were both rated at 560 hp. It could be the transmission as the shifts of the Ferrari felt at least twice as fast as the ones in the SLS. The Scuderia version is rumored to have forced induction so it may be more potent as well.

I just can't see that happening unless its turbos ?? A blower would ruin it on the track and that's what the Scuds are made for. I'm pretty sure it will be NA but tweaked a bit like previous versions. And yeah...the Scud transmission is sick fast plus the weight advantage.

The idea is for a track car and the NA powerplant makes far more sense. Nobody wants limp mode after a lap.

They both have dual clutches so it really isn't shift speed as the limitation with those transmissions really is just the speed at which you can move something mechanically at this point. We are talking shifts for both 30 times faster than you can blink your eye.

The weight and launch due to a mid engine layout were likely the primary factors. The SLS also dyno's more horsepower I believe but I'm too lazy to go dig out it out right now.

No way Ferrari would do a supercharger. Turbos? Interesting, but no previous version of any Scuderia or Challenge Stradale went the route of forced induction. Instead, Ferrari reduced weight and optimized the poewerplant already used. It makes sense for them to repeat this precedent. I haven't heard any turbo rumors other than for the next generation of cars. Too much is already invested in the current motor.
